Seems to do it's thing well. Would love to see notes by URL. That's what the old Sticky Notes add-on did and it was really useful. As it is, it's still useful but could be wickedly powerful if associated with a specific page...

It is very lagging when you add a lot of text

This extension is really cool, & should be incorporated as a standard feature of ff ( along with vertical tabs in the sidebar & per-page RAM deallocation ). ( Extensively tried in Linux & Windows10 ).

And it doesn't pilfer my private data. Viva la libre!

really good idea--BUT sync doesn't work correctly, very buggy sync, and very slow laggy performance with latency in typing or copying text makes it impossible to use.

Notes wäre ein praktischer Zusatz, die Idee ist perfekt - dass es sich aber manchmal mehrmals täglich wieder ausloggt, nervt ungemein. Ich nutze es aus diesem Grunde fast gar nicht mehr.

20.10.: Hab's gerade deinstalliert. Das ständige Einloggen nervt und das Tool ist zu unzuverlässig. Meine gesamten Notizen von gestern sind gerade beim Wieder-Einloggen verschwunden.

If only you can add a "Sync" feature to the cloud, it would be a Five Star.

I really loved this extension, the only cons i found was some bugs on the extension and the android app wasn't released yet

unfortunately I need to register every time I start the notes app on my Android phone since last update. That makes it useless for me. Before it was a simple but helpful tool.

Notes erweist sich als praktischer Zusatz für eigene Notizen und Ideen. Es ist unnötig geworden, dazu extra einen extra Editor zu starten und seine Gedanken und Ideen damit notdürftig festzuhalten. Praktisch ist die Buttonleiste zum Formatieren des Textes. Das erspart einem den ansonsten immer wiederkehrenden Blick auf die "Mark-Up"-Kürzel.
Statt dem Button "Durchgestrichen", wäre zum zusätzlichen Hervorheben besonders wichtiger Inhalte, ein "Unterstreichen" oder "doppelt Unterstreichen"-Button perfekt. Alles in allem erfüllt es somit fast perfekt meine persönliche Vorstellung eines solchen Tools.

I really like this. Minimal and clean. A AMOLED/Black mode would be great for desktop and mobile. The ability to insert photos would also be nice.

Eine gute, wenn auch noch sehr einfache Notes-App. Besonders stört mich an der aktuellen Version, dass sich Notes sowohl auf meinem Laptop wie auf meinem Handy immer wieder selbst ausloggt und ich den Login immer wieder per Mail bestätigen muss.

Un componente aggiuntivo 'essenziale' per prendere note. E' possibile modificare, eliminare e formattare il testo in maniera semplice, non a livello di un 'word processor' ma va più che bene. Non è possibile aggingere allegati, ma a mio avviso è una funzionalità secondaria che appesantirebbe il tutto. E' possibile soltanto sincronizzare in cloud avendo un account Firefox. Sarebbe opportuno, a mio avviso, che le note potessero essere ordinate in vario modo. Di default soltanto in ordine di immissione (data-ora).
PRO
> Intergrazione con Firefox e sincronizzazione in automatico con Firefox account;
> Formattazione delle note, anche se un pò semplice, ma è possibile ovviamente inserire link sottoforma testuali, quindi niente "collegamento ipertestuale";
CONTRO
> Non è possibile organizzare le note ad esempio in ordine alfabetico o altre modalità;
> Menù laterale spartano. E' possibile soltanto aggiungere note, esportarle in HTML ed eliminarle;
> Non è possibile importare note. Il salvataggio è solo in cloud se si ha un account Firefox, che comunque è gratuito.

I request you to increase the speed... it lags a lot when a note file is huge... it happens in both the web and app versions.

The inability to create folders makes this potentially useful extension one of very limited usefulness.
